No phosphateBy Michael on 7/29/2015

Had a problem starting with bubble algae and one problem area with turf algae. Ordered and used this in a BRS reactor SUPRISE no more algae and no phosphate. Works great, just use less than recommended at first so you don't shock your system. Takes about 3 gallons of RO to flush fines and rust color from the water. Ordered more when I ran out and will continue to use it.

Best GFOBy Shawnon 7/4/2015

Shawn would recommend this product to a friend

One of the best ways to drop those nasty phoshate levels in a hurry. I honestly never tried another brand but I don't intend to if BRS keeps making quality GFO.

Very important piece of the algae free puzzle.

Slightly larger pellets are awesome. By Turfon 6/7/2015

Turf would recommend this product to a friend

The slightly larger pellet size has made it substantially easier to deal with in a filter sock or reactor the ones I've used in the past.

Brs Gfo is affective and very easy to use. Just follow the instructions on the container or hit up BRS online and the calculator with help you out.

Worth itBy Soseeon 5/21/2015

a good value but don't use the amounts they recommend in the reactor. I followed the advice of a seasoned reefer and used half the recommended amount and it works great! Using too much can effect your alk levels.

I'm assuming by my lack of green dlime and hair algae it has worked as promised. Thanks

It really does mean granular By Jameson 5/13/2015

James would recommend this product to a friend

I've only had the GFO in for about a week now but I've been testing every day (too much time on my hands) and my phosphate level is definitely on its way down. Not enough time yet to say anything about the algae, but science doesn't lie. I only have one thing, filter socks don't work with this. I put it in and started to rinse it out and it started coming out of the sock like dust (which it is). But that's my lack of experience, not the product.

A must for reefBy Deafclownon 5/6/2015

I wish I had used this in the beginning! I believe it's a must have for a reef to help keep phosphate down and calm the algae growth.

This stuff rocks! Keeps my phosphates at 0. I change it once a month, though I am sure it would last longer if I left it. Never hardens or clogs. Love it!!

PRICE AND QUALITYBy machoteon 3/27/2015

machote would recommend this product to a friend

very good product i used to run a ATS (alggae turf scrubber) it was great but so much evaporation and maintenance needed each 7 days, also you need to design it very well and do a lot of research ( i spend a lot of hours? a lot of $ on light because u need a watt for gal now imagine in a 300 gal reef tank, also water splash etc, this gfo does the same but less work so then this is GREAT no maintance needed just replenish each month or month and a half

I was watching Mr Saltwater Tank on u-tube ,he turned me on to bulk reef supply. I was having a big algae problem . He said to use BRS bulk Gfo in a reactor .The algae was out of the tank in 3 day /with light out . Wow this is the best my 15 year old tank has ever looker. Also it was a great price and was shipper very fast. Will buy all my need from BRS

ExcellentBy luison 2/15/2015

luis would recommend this product to a friend

This works very well and I have only been using my gfo from brs. Very straight forward I run mine in a canister along with brs carbon in another canister I simply fill, install open my ball valve and rinse with tank water until dust particles at minimal or just until water comes out clear so it helps with a 1-2 gallon water change in my total 90g reef. Also I only have to change it every month and a half to two months on my bio load very good. Thanks BRS!

Started using this GFO in a BRS single reactor mixed with Carbon after having a green dust algae bloom in a newly established reef. I noticed differences the next day. Removing the phosphates completely killed off the algae within a week. Thanks for the advice BRS, good media!!!
